RIM-ENGAGING DEVICE Application filed August 21, 1908.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Serial No. 449,721.

To all whom it may concern:

Be it known that I, Hnnvn T. A'NDREW, a citizen of the United States, residing at Baring, in the county of Knox and State of Misssouri, have invented a new and useful Rim- Engaging Device, of which the following is a specification.

This invention relates to an improvement in rim engaging devices and is intended for use with lifting jacks.

One object of the invention is to provide a novel, simple and efficient support which is particularly designed for removing and replacing the brasses in the journal boxes of freight, passenger, and other cars, and which is so constructed that it can bear against the shoulder formed by the concave part of the car Wheel in proximity to the tread and thus avoid the usual practice of raising the entire trucks to move the wheels and axles downwardly in order to replace or repair certain parts within the boxes.

With these and other objects in view, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the device may be made without departing from the spirit or sacri- 'ficing any of the advantages of the inven tion.

In the accompanying drawings forming part of this specification: Figure 1 is a vertical section taken through an ordinary car wheel and journal box showing my device applied thereto. Fig. 2 is a perspective view of the device.

Similar numerals of reference are employed to designate the corresponding parts throughout.

The invention consists essentially in a platform adapted to support a pair of vertical jaws, which are adapted to straddle the journal box so as to prevent the same from swinging laterally when supported by a jack.

'A platform 1 preferably formed of metal substantially rectangular in marginal contour, is designed to be suspended above the ground. Rising from each of the longitudinal sides of this platform is a vertical jaw 2 and 3. These jaws are adapted to straddle an ordinary axle box 4t as shown in Fig. 1, it being understood that the width of the platform 1 and the height of the jaws will be 1 sufficient to permit the performance of this function. By referring now to Figs. 1 and. 2 it will be observed that the width of each jaw at its base is considerably less than the length of the platform 1, and that side of each jaw adjacent the free end of the platform curves inwardly from its base to the upper end thereof. The opposite side, or that farthest from the free end of the base 1 is, at a point adjacent its horizontal center curved backwardly and toward the inwardly curved side 5, the function of this construction will appear later. The jaws are connected by a vertical wall 6 which rises from that end of the platform 1 opposite the free ends, to a height approximately in a plane with the horizontal centers of the jaws 2 and 3. Formed integral or otherwise secured to the outer face of the wall 6 is a foot piece 7 disposed approximately in a plane with the longitudinal center of the wall, and extendin g from the upper edge thereof downwardly to a point adjacent the horizontal center of the wall; the lower edge of this foot piece is squared and extends at right angles to the outer face of the wall 6. It is designed that the width of this foot piece will be sufficient to permit it to engage the concave part of a car wheel as illustrated in l 1. In the use of the device the free ends of the jaws 2 and 3, are brought to straddle the axle box behind the usual tie bars, (not shown),by now forcing the device to a vertical position the foot piece 7 will be brought in position to rest on the shoulder of the wheel as illustrated in Fig. 1, and the base 1 will be held suspended above the ground. \Vhile the parts are in this position a suitable jack is placed upon the platform 1 directly beneath the center of the journal box. By now turning the head in the usual manner in order to bring the same into engagement with the journal box the latter and trucks to which it is fixed will be raised in the desired. manner, while the wheel and axle will remain in their normal horizontal planes. By forming the outer edges of the jaws 2 and 3 so as to curve inwardly permits the usual handle, used for turning the head of the jack to be employed.

What is claimed is 1. In a rim engaging device, a platform provided with vertical jaws to straddle a boxing, a wall connecting said jaws, and a rim engaging foot piece on the outer face of said wall.

2. In a rim engaging device, a jack platform provided at one end with vertical jaws to straddle a boxing, a wall connecting said jaws, and a rim engaging foot piece intermefiiately disposed on the outer face of said wa 3. A rim engaging device embodying a member provided with a jack platform, a pair of vertical jaws carried by said platform, avertical wall at one end of said platform the sides of which are connected to the opposed inner faces of said jaws, and a foot piece disposed on the outer face of said wall and extending beyond the vertical plane of said aws.

4. A rim engaging device embodying a member provided with a jack platform, a pair of vertical jaws carried by said platform, a vertical Wall at one end of said platform the upper edge of which is adjacent the horizontal centers of saidwalls, a foot piece on the outer face of said wall having its lower edge extending outwardly and at right angles to the vertical plane of said jaws.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature 5 in the presence of two witnesses.
